# GAIN

The 5K supports user-selectable amplifier gain modes.

* **Normal**   
  * UNBAL 1VRMS / BAL 2VRMS
  * Longer battery time and lower noise floor

* **High**        
  * UNBAL 2VRMS / BAL 4VRMS
  * Maximum output level increased by +6dB

{% hint style="info" %}
**N**The current volume (output level) is adjusted to remain consistent when switching between Normal and High modes.
{% endhint %}

{% hint style="info" %}
Both modes provide the same sound performance. Normal mode is recommended in most cases if the output power is sufficient.
